HAT-PRESS.

Specification of Letters Patent. Patented Aug- 29, 1916 Applicationfiled July 29, 1915. Serial No. 42,507.

To all whom it may concern Be it known that I, LEO GALITZKI, Jr., acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Hat-Presses, of which the following is a specification.

My invention relates to improvements in hat presses, whereby to press orblock hats.

One of the objects of my invention is to generally improve, simplify andcheapen the construction of presses of this character, to the end thatthey may easily and quickly be operated; that their cost of productionmay not be prohibitive; that the interior may be visibly presented tothe operator when the press is open, and that the parts carrying theexpanding die may thus be entirely removed and out of the way at thetime when the operator is placing the hat in the shaping die.

Other and further objects of my invention will become readily apparentto persons skilled in the art from a consideration of the followingdescription when taken in conjunction with the drawings wherein Figure 1is a front elevation of the press and the stand upon which it ismounted. Fig. 2 is a side elevation of the press, with the legs brokenaway. Fig. 3 is a plan view. Fig. 4 is a central section taken throughthe press showing it open.

In all the views the same reference characters are employed to indicatesimilar parts.

The press 5 is mounted upon a stand 6, the latter is composed of fourvertical legs 7, and connecting rungs 8, made preferably of gas pipe, tohold the legs in separated positions. Each leg is, preferably, providedwith a flange 9 to afford a better base upon which the stand may rest.

Secured to the two rear legs of the stand are angle bars 10 and 11,carrying at their upper ends a shaft 12, upon which is mounted a groovedrope pulley 13. The legs 7 are joined together at their top ends byangle bars which afford a base upon which the press 5 rests.

The press proper is divided into two major parts; the fixed steamjacketed part 16, which rests upon the stand, and a pivoted movable part17 which is pivoted to the fixed part as at 18 and which is lifted by acounter weight 19 through the instrumentality of the rope 20 whichpasses over the pulley 13 and which is connected to the upper portion 17of the press by an eye 21.

The upper hinged portion 16, of the press, is provided with a forwardlyprojecting nose 22 which has association with the pivoted latch member23, pivoted to the lower portion 16, as at 24, and having a portion 25projecting forwardly to overlie the nose 22 when manually moved by thehandle 26. This latch holds the parts together and prevents theirseparation when pressure is applied in the process of forming the hat.

The base portion 16 of the press carries a fixed die 27 which determinesthe shape of the hat. The die 27 may be lined with a more or lessflexible porous lining 28, such as felt or the like, into which the hat29 is placed when it is to be blocked or pressed. The relatively thickportion 16 of the die is provided with a steam jacket 30 communicatingwith which is a steam pipe 31, which is controlled by a globe valve 32.

The open hinge portion 17 of the die is conoaved on its under side toprovide a fluid space 33. A diaphragm 34 of yielding material such asrubber, partly closes the cavity 33. It is, however, provided with anopening 35 near its center, its outside edges being included between aflange 36, of the part 17, and a removable ring 37, secured to theflange, as by bolts 38-38. A ring of felt 39, is placed between thediaphragm and the ring 37 to protect the diaphragm. A hat-like die 40,made preferably of rubber, or other similar material has somewhat theshape of the hat to be pressed and is secured to the diaphragm 34,around the edges of the orifice 35, and is adapted to enter the hat whenthe part 17 is placed in contact with the thick part 16 of the press. Awater compressing device 41 provided with a handle 42, of the usual typeis connected with the cavity 33 in the upper portion 17 of the press, bymeans of a flexible conduit or hose 43. A pressure gage 44 communicateswith the interior of the upper portion 17 of the press and indicates tothe operator the amount of pressure that is being applied to the press.

To press a hat, substantially as hat 29 shown in the press in Fig. 4, itis only necessary to place the hat in position in the die 27, the pressis then closed when the rubber, or other yielding form 40, will enterthe hat. The latch 23 is then brought into position shown in Fig. 2,when the two parts of the press will be tightly held to gether. Theflange 37 has a rim 37 which enters a cavity 16' in the part 16. Thisprovides a tortuous passage for the water that may escape through theflange 3 1 and the die 35 and be contained between the two parts of thepress and prevents its escape and at the same time it forms a guide wayto hold the two parts of the press in proper register while it is beingoperated.

When the two parts, 16 and 17 of the press, are brought together, steamhaving previously been admitted into the cavity of the lower portion 16of the press, water under pressure is now admitted into the cavity 33 ofthe upper portion of the press which forces the yielding die 30 intointimate contact with the hat 29 and causes it to assume the shape orform indicated by the die 27.

When it is desired to remove the hat from the lower portion 16 of thepress it is only necessary to throw the latch 23 over out of engagementwith the nose 22, as in the position shown in Fig. 4, when thecounterweight 19 will automatically raise the press into the positionshown. When in this position every part of the press, as well as thecontents, is presented to view and is freely accessible and the press iscapable of being opened and closed in much quicker time than presses ofthe ordinary construction.

Having described my invention, what I claim is 2- In a hat press thecombination of a base portion 16,'having a central depression for a dieand having an annular groove 16 in its boundary Wall; a hinge portion 17having a cavity 33; a diaphragm 341 overlying the cavity, and carrying adie 10; a clamping ring 37 overlying the marginal edges of the diaphragmand having an integral rim 37 which enters the groove 16 when the pressis closed to provide means to hold the dies against relative lateraldisplacement and to prevent escape of steam or water from the interiorof the press.

' In testimony whereof I hereunto set my hand in the presence of twosubscribing witnesses.
